Musannaf Ibn Abi Shaybah 31332 — The greatest name of Allah

Sayyiduna Buraydah (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) heard a man supplicating thus: "O Allah, I ask You by means of the fact that You are Allah, the One, the Self-Sufficient, who has not begotten and was not begotten, and to whom no one is equal." He (peace and blessings be upon him) said: "This man has asked by means of the Greatest Name of Allah, such that when He is supplicated by means of it He answers, and when He is asked for something by means of it He gives."
